Converting some or all CSS port networks to IP-PNC
The converted configuration
The final converted configuration can be all IP-PNC or mixture of IP-PNC and fiber-PNC. The
reliability level for the fiber-PNC portion of the converted system can be Duplex, High, or
Critical. The reliability level of the IP-PNC portion of the converted system is per PN and can
also be Duplex, High, or Critical. That is, some IP-PNC PNs can have duplicated control
networks while other IP-PNC PNs have nonduplicated control networks. Still other can have
duplicated bearer. See
networks (with S8700-series Media Servers only)
If synchronization is required for any of the IP-PNC PNs, the synchronization source must be
administered separately for each IP-PNC PN.

Important:
Avaya recommends that you perform a traffic analysis when changes from a
Important:
fiber-PNC configuration to a mixed configuration that includes both fiber-PNC
and IP-PNC PNs. A traffic analysis helps you understand Inter-PN bearer traffic
and determine the correct number of media processor resources, other network
parameters such as the use of network regions, codec sets, and VLANs. For
more information, see Avaya Application Solutions: IP Telephony Deployment
Guide (555-245-600) and Administration for Network Connectivity (555-233-504).
Configuration Diagrams
on page 1105 provides sample before-and-after diagrams for the conversion of a CSS
configuration from fiber-PNC to IP-PNC.
For the starting configuration that is shown in
S8700-series CSS with duplicated control networks
duplicated and the bearer network is fiber-connected through a CSS. The converted
configuration that is shown in
S8700-series with mixed reliability — converted from CSS configuration
mixture of fiber-PNC and IP-PNC PNs. Two of the PNs were converted to IP-PNC and the
remaining PNs are fiber-connected through the CSS. All PNs after conversion, except PN 19,
have duplicated control networks.
Figure 82: Example of MCC1 Media Gateway with IP-PNC and mixed reliability
shows an MCC1 that is converted to an IP-PNC configuration. The MCC1 contains three
PNs:(1) carrier A, (2) carriers B and C, and (3) carriers D and E. PNs (2) and (3) have
duplicated IPSIs and control networks and are thus at the high-reliability level. PN (1) has a
single control network and is at the Duplex reliability level.
Variations on these configurations include mixed PNC and mixed reliability starting and
converted configurations.
